Question

select all the correct answers.
what happens at locations where magma convection currents flow away from one another?

overlying, adjacent plates collide violently.

groundwater rises to the surface.

new crust is formed along the boundary.

oceanic plates slide beneath continental plates.

overlying, adjacent plates are pulled apart.

Explanation:

• When magma convection currents flow away from each other, it occurs at divergent plate boundaries.
• At divergent boundaries, the overlying adjacent plates are pulled apart (so this option is correct).
• As the plates pull apart, magma rises to fill the gap and new crust is formed along the boundary (so this option is correct).
• Plates colliding violently is at convergent boundaries (so the first option is incorrect).
• Groundwater rising to the surface is not related to magma convection currents pulling plates apart (so the second option is incorrect).
• Oceanic plates sliding beneath continental plates is subduction at convergent boundaries (so the fourth option is incorrect).

Answer:

C. New crust is formed along the boundary.
E. Overlying, adjacent plates are pulled apart.
